Years ago, I didn't believe it.
Then, I considered intelligence to be about the seeking of balances. Some are able to focus on matters of importance to others, and being able to articulate that they gain deserved attention, at least for the duration of the high importance of the subject.
Eternalists, seeking the broadest definitions, need to also communicate with others, be they Eternalists or not, their way of Eternalist thinking, the mindset of expansion and balances. This is not the same thing as recruiting, but then in it should not exclude recruiting for whoever expresses a desire to join us. A person HAS TO BE READY to come into the Eternalist mindset, but never pursue those who express serious doubts. If you can't make them grow, you have to leave them behind. This might not be their lifetime to embrace the light of never-ending Time. Perhaps the next one.
